debugging 6TB Seagate SAS drives that `lost async page write`

comments.md

Note the script is available at the bottom. See u/fmillion's post in r/homelab for my inspiration to explore down this path. My debugging efforts from before that are noted at https://gist.github.com/altendky/96fe6c1f799fdbf79516f9528d6fd644.

I have 6x 6TB Seagate SAS drives (ST6000NM0034 / DKS2F-H6R0SS, 7FA6 firmware) that came to me with 520 byte sectors. I have reformatted them to 512 first with sg_format then with the SeaChest tools. I still get /dev/disk/by-id/scsi-SSEAGATE_DKS2F-H6R0SS_Z4D1V24X0000R535X9WQ: close device failed: Input/output error and lost async page write when fdisk tries to write a new partition table. mkfs straight on the disk fails as well. They are on a Super Micro backplane attached to a pair of LSI SAS9210-8i (BIOS 07.39.00.00 and firmware 20.00.02.00 per systool). I do have a standard old 3TB SATA that I have tested in the same setup that worked. Presently only the single problematic 6TB is installed on the backplane. Any ideas where I should go next?

Here is another seemingly similar case. https://www.hardwareluxx.de/community/threads/seagate-st4000nm0175-unter-linux-nutzbar-machen-520-512.1281780/

H6R0SS indicates an Hitachi drive. Correct? After all my investigation it seems the special Hitachi firmware locks any write access outside of the storage array. Our only chance to make it work would be installing the "original" Seagate firmware. But I had no suceess doing so.

Btw: It MAY be possible to SECURE format those with a Dell/EMC H700 controller. No sure if it's worth investing those $20 just to test another dead end ...

i have same problem i have dumped my firmware spi chip here's a link https://github.com/redwoodimage/seagate/

@redwoodimage: If you say you dumped it: Have you been able to flash ANY other firmware to those disks? I'm struggeling to even find out what kind of disk this really is. Mine is a 5 platter 4TB disk and should be an EXOS, but there is no 5 Platter with 800GB/platter in this series. Quite confusing.
